Discussion

Variety septentrionale is an arctic-alpine taxon. In arctic North America there is a correlation between capsule shape and leaf serration, plants with distinctly serrate leaves having ovoid-cylindric or cylindric capsules, whilst those with entire or subentire margins have subglobose or ovoid capsules (D. G. Long 1985).
